BACKGROUND OF THE INVENTION

1. Field of the Invention

Embodiments of the present invention generally relate to a method and system for processing gestures to cause computation of measurements of an angle or a segment using a touch system.

2. Description of the Related Art

In a touch system, measuring segments and angles is cumbersome. Angles are generally defined by three (3) points. Calculating the measurement of an angle generally involves multiple steps—accessing the menu, choosing a measurement tool, and then touching the three points defining the angle.

Therefore, there is a need for a method and/or apparatus for processing gestures to cause computation of measurements of an angle or a line using a touch system.

SUMMARY OF THE INVENTION

Embodiments of the present invention relate to a method and a system for processing gestures to cause computation of measurements of an angle or a segment using a touch screen. The system includes a processor, a touch screen coupled to the processor, a gesture module coupled to the processor for executing gesturing method, the method includes determining a gesture shape, when the gesture shape is an arc between two touching lines, calculating the angle between the touching lines behind the gestured line or arc, when the gesture is a line crossing a segment, calculating the measurement from the beginning point of the segment to the end point of the segment, and displaying the calculated measurement of at least one of the angle or the segment.

DETAILED DESCRIPTION

Utilizing a touch screen, the user slides fingers, a pointer or the likes from one line to another. In some embodiments, a touch screen is a screen that is capable of recognizing a gesture without necessary requiring an actual touch of the screen, such as, a gesture of hand, finger, stylus, motion, etc. In other embodiments, a touch screen is a screen that recognizes a gesture from actually touching the screen. FIG. 1 is an embodiment of a diagram depicting a gesture for triggering calculating an angle using a touch scream. In FIG. 1, an embodiment of an arch or a line drawn from one line of the angle to the other is depicted. As shown in FIG. 1, the user gestures an arch or a line from line AC to line AB or from AB to line AC to calculate angle CAB or BAC. Though, in some embodiments that lines touch, in other embodiments, the line form an angle but do not touch.

FIG. 2 is an embodiment of a diagram depicting a calculation of the angle of FIG. 1. As shown in FIG. 2, a method or system coupled to the touch screen recognizes the gesture and computes the angle's measurement, which is shown in FIG. 2 to be 56.4°.

Similarly, utilizing a touch screen, the use slides a finger, a pointer or the likes across a segment. FIG. 3 is an embodiment of a diagram depicting a gesture for triggering calculating a segment using a touch scream. In FIG. 3, an embodiment of a line drawn across a segment is depicted. As shown in FIG. 3, the user gestures a line crossing segment DE to calculate the measurement of segment DE.

FIG. 4 is an embodiment of a diagram depicting a calculation of the segment of FIG. 3. As shown in FIG. 4, a method or system coupled to the touch screen recognizes the gesture and computes the measurement of the segment from the segment's beginning point to its end point, which is shown in FIG. 4 to be 7.17 cm.

FIG. 5 is an embodiment of a flow diagram of a gesturing method 500 for processing gestures to cause computation of measurements of an angle or a segment using a touch system. The method starts at step 502 and proceeds to step 504, wherein the method 500 determines the shape of the gesture. At step 506, the method 500 determines if the gestured shape is an arch or line between two lines touching lines. If it is, then the method 500 proceeds to step 508, wherein the angle between the lines and behind the arch or line is calculated. Otherwise, the method 500 proceeds to step 510.

At step 510, the method 500 determines of the gestured shape is a line that intersects a segment. If it is, then the method 500 proceeds to step 512, wherein the measurement between the beginning point and the end point of the segment is calculated. Otherwise, the method 500 proceeds to step 516. From steps 508 and 512, the method 500 proceeds to step 514, wherein the calculated measurements are displayed and the method 500 proceeds to step 516. The method 500 ends at step 516.

FIG. 6 is an embodiment of a gesture system diagram utilizing the method of FIG. 5. The gesture system comprises a processor, a gesture module and a touch screen. The processor is capable of executing instruction to perform functions, such as, calculating measurement, determining gestures from a touch screen, and the like. The gesture module performs such method as the method 500 Of FIG. 5. The touch screen is coupled to the processor directly, indirectly or wirelessly to facilitate gesture recognition and/or determination by the gesture system.
